SUPR-Q Background

The SUPR-Q (Standardized Universal Percentile Rank) Measures the Essential Aspects of a Website in just 13 multiple choice questions.

It was developed through a process called psychometric qualification where the best 13 items from a pool of 75 candidate items were identified. The items were winnowed down by only retaining those which generated high internal reliability, loaded highest across common factors, had the highest item-total correlation and could discriminate best between websites.

The database contains responses from almost 10,000 participants across 200 websites.

Usability: If users can't accomplish what they want to do, find the product they're looking for, or complete their purchase--it's like the information or product doesn't exist. A usable experience means a profitable experience.

Credibility (Trust, Value & Comfort): Does the website sell products and collect credit card information? Are you gathering email addresses to build a subscriber base? If users don't trust your website, which for many companies is synonymous with their company and brand, they won't give up their information and website growth is impeded.

Loyalty:Are users talking about your website favorably or are they telling their friends to avoid it like the plague? Will they return to the website and purchase more things or at least see what you have to say? These two items touch upon repeat usage from existing customers and net-new usage from new customers.

Appearance: Is your website looking circa 1998 and is the appearance hindering the experience? Users form impressions of your website based on the appearance in just a few seconds.
